Statement of the Problem/Objectives This study aims at making malunggay leaves extract a cockroach killer. It has specific questions to be answered: a) Can malunggay leaves extract be used as a cockroach killer? b) Can people use malunggay leaves extract as a cockroach killer as effectively as commercial insecticides? General Objective: 1. To investigate whether malunggay leaves extract can be used as a cockroach killer. Specific Objectives: 1. To be able to use

The pesticide must be diluted with water‚ oil‚ air or chemically inactive solids so that it can be handled by application equipment and spreas evenly over the area to be treated. It includes cockroach killer. Malunggay called “Malunggay” in the Phippines‚ “Sajina” in the Indian Subcontinent‚ and “Moringa” in English‚ it is a popular tree.

Tropical cockroaches are often much bigger‚ and extinct cockroach relatives and ’roachoids’ such as the Carboniferous Archimylacris and the

investigate the effect of application of propoxur (a carbamate insecticide) on the American cockroach. From experimental observations‚ it has been concluded that the amount of propoxur needed to kill 50% of the test subjects (referred to as LD50) was 0.0487(%w/v) which deduces to be 0.22012mg per cockroach (calculated for 0.452grams of cockroach). The conclusions were drawn immobilising the American cockroach with ice then applying propoxur to be incubated at 23 degrees Celsius. Literature findings

In this experiment‚ it was found that there exists a spontaneous resting activity within the cockroach tibia even though tactile sensilla receptors have not yet been stimulated. From figure 1 it can be observed that the mean spontaneous resting activity of the cockroach leg is (42+/-9.7) action potentials/sec. After the tactile sensilla receptors were stimulated by moving the receptor

The three temperature environments conducted in the experiment included room temperature‚ a cold environment (ice bath)‚ and a hot environment (how water bath). The purpose of this study was to test the effects of temperature change on the ectothermic organism Madagascar Hissing Cockroach (Gromphadorhina portentosa)
